Each year hundreds of thousands of population find themselves victim to some form of cancer. Caused by whether environmental toxins or genetic disorders, the occurrence of cancer has risen in up-to-date years. A report created by the National manufacture of health estimated the extensive cost of cancer to be 3.8 billion in curative costs. This includes direct curative costs, morbidity costs, and indirect mortality costs. Since all forms of thorough cancer rehabilitation are incredibly invasive (chemotherapy, radiation therapy, and surgery) and plagued with side effects, alternate methods of rehabilitation are all the time being sought after. One exciting new choice is rehabilitation with Vitamin E tocotrienols. Any preliminary studies have been conducted showing the inherent for this vitamin in hereafter cancer rehabilitation plans.
Tumor Growth
Vitamine
In order for a tumor to grow beyond 1 to 2 mm in diameter, it needs some sort of independent blood supply. Without this, the cancer tumor cannot spread and tumor growth stops. The creation of new blood vessels is termed angiogenesis. Tumors are able to issue growth factors that commence angiogenesis which causes existing blood vessels to generate new 'branches' that supplies the tumor with a blood supply.
Studies have shown that one of the mechanisms in which tocotrienols uses to preclude cancer metastasis is angiogenesis inhibition. Delta- and gamma- tocotrienols are especially marvelous in this respect. The other form of vitamin E, tocopherols, do not show this ability.
Breast Cancer
Breast cancer ranks second as the cause of cancer death in women. Each year an estimated 275,000 new cases and practically 41,000 deaths occur in the United States. thorough breast cancer rehabilitation involves the drug, Tamoxifen. Tamoxifen is a widely used hormone therapy. Although quite useful in treating breast cancer, tamoxifen does have its inherent risks. Long term rehabilitation with the drug increases a woman's opportunity (albeit a rare chance) of developing serious health problems: endometrial cancer, blot clot in the lungs, and blood clot in major veins.
Several studies have been done on tocotrienols ability to treat breast cancer. A 1998 publication in the Journal of nutrition and Cancer confirmed that delta-tocotrienols are capable of inducing cell apoptosis (cell death). an additional one study published in the journal Bmc Cancer showed that gamma-tocotrienols in conjuncture with anti-cancer drugs cut breast cancer cell growth in mouse breast cancer cells in culture. Yet an additional one study showed that gamma-tocotrienols were able to preclude an implanted tumor from taking hold in a mouse specimen.
Prostate Cancer
Prostate cancer is most commonly diagnosed cancer among men in the United States and the third most tasteless cause of cancer death among men. Research done by Davos Life Science, researchers at Australian Prostate Cancer Research Center, and Hong Kong University showed that gamma-tocotrienols not only reduced tumour size, but also decreased the incidence rate of tumor formation by 75%. They compared this to a operate group of mice, which had 100% tumor formation. This study is foremost because prostate cancer stem cells (the precursor to the cancer tumor) is unyielding to accepted chemotherapy drugs and thus very difficult to manage.
Pancreatic Cancer
Pancreatic Cancer causes 30,000 deaths per year in the United States. Pancreatic Cancer is a very potent cancer, with fewer than 5% of those diagnosed still alive five years after diagnosis. It is very rare and fortuitous for a faultless remission of the disease to occur.
An animal study done by researchers at Md Anderson Cancer town have shows that combining gamma-tocotrienol with chemotherapy boosted the effectiveness of the drug in dealing with the tumor. In prostate cancer, the protein complicated Nf-KappB is hijacked by the cancer cell. Nf-KappB usually controls our cellular response to stress and plays a key role in regulating the immune system. Once the tumor takes over Nf-kappB it starts using its same mechanisms to defend itself. Drugs that can selectively target Nf-kappB would be too toxic for our health. The only other ready alternative for dealing with the tumor is with nutrition. Tocotrienols can differentiate in the middle of a cancer cell and a normal cell and thus alter Nf-kappB accordingly.
A partial intuit tocotrienols are productive against pancreatic cancer is because it can fetch in the pancreas 10x more than in other parts of the body such as the liver or even the tumor itself. Despite this accumulation, a study in mice was done to show that no observed toxicity or side effects occurred from delta-tocotrienol administration.
Other Cancers
Palm oil tocotrienol reduced cervical cancer in vitro. An in vivo and in vitro study showed suppresion of liver and lung carcinogenesis in mice. Gamma- and delta-tocotrienols were also shown to inhibit melanoma cancer cells in vitro.
Closing thoughts
The inherent for tocotrienols to act as a natural source to deal with cancer is very exciting. Of course, more human studies need to be done before they come to be a thorough form of treatment. One last thing to note is that a multimillion dollar grant by the National Cancer manufacture was recently awarded to the Moffitt Cancer town and Research manufacture to guide clinical trials on tocotrienols' result on pancreatic cancer.
